Hello, my name's Jorge, I am an electronics engineer with 4 years of experience writing firmware for embedded devices.
I have read the description of your project. I have completed a similar project requiring to connect several pi boards to a "custom arcade" used for escape rooms. I'd like to get more information about the parts that the system will control, that is, the small blower, the color scanner and the projector. Also, do you have already a scanner for the driving licenses? or this is to be investigated as part of the project?
The main overview of the implementation would be to have a pi server that can control the rest of the devices in the network, and save the information about lottery timings in a database. Do you have an overview of the implementation of the complete system?
Please share with me more details of your project, I'd like to know the current status of it (like, for example, have you selected all hardware parts?) and read more from you so we can start working on your project as soon as possible.
Thanks in advance for your time.
